Method of treating the hair with an allanoyoin-panthenol product

Abstract

A composition containing allantoin, panthenol, and an monohydric alcohol is obtained. The composition is useful for treating hair.

What is claimed is: 
     
       1. A method of treating hair, including the steps of forming a product comprising: (1) (A) dispersing panthenol in a monohydric alcohol at a temperature above the melting point of the panthenol to obtain a liquid melt; (B) dispersing allantoin in the liquid melt of (A) at a temperature above the point at which the liquid melt is in the liquid phase to obtain the product,     (2) applying the product to the hair in a sufficient amount; and   (3) activating the product by heating the hair for a time and at a temperature sufficient to achieve substantive application of the product to the hair.   
     
     
       2. The method of claim 1, wherein the alcohol contains from 12 to 18 carbon atoms. 
     
     
       3. The method of claim 1, wherein the panthenol is present at a weight ratio to the monohydric alcohol at a 70:30 to 30:70 weight ratio. 
     
     
       4. The method of claim 1, wherein the temperature at which the panthenol is dispersed in the monohydric alcohol is between 65° C. and 105° C. 
     
     
       5. The method of claim 1, wherein the alcohol is a primary alcohol. 
     
     
       6. The method of claim 1, wherein the weight ratio of component (B) to component (A) is from 5:95 to 35:65. 
     
     
       7. The method of claim 5 wherein the alcohol is 1-tetradecanol. 
     
     
       8. The method of claim 1 wherein the amount of the monohydric alcohol in (A) is less than or equal to the amount of panthenol in (A). 
     
     
       9. The method of claim 1 wherein the panthenol reacts with the allantoin. 
     
     
       10. The method of claim 1 wherein the product additionally comprises a member selected from the group consisting of water, gum, kaolin and titanium dioxide and mixtures thereof. 
     
     
       11. The method of claim 10 wherein the member is water in a weight ratio of about 1000:1 to 99:1. 
     
     
       12. The method of claim 11 wherein the product has a pH of 3 to 9.5. 
     
     
       13. The method of claim 1, wherein the temperature of activation is about 20° C. to about 75° C. 
     
     
       14. The method of claim 1, wherein the product is applied to the hair at about 1 gram per 1000 grams of hair.
